Someone help me in the right direction for networks <- Might be off topic

Hi, 
I've been asked to set up a network of between 6 and 10 computers, using linux yet i don't know what to do. I've decided to allocate 2 as servers and because we have to run our network with in another network so we are hoping to run the 1 server as a copy of the other one just it will be sitting outside of the firewall(not allowed to open other ports on the firewall) so we can access documents at home, i'm thinking of running a webdav server to do that part.. Now the main problem how would i go about configuring the workstations to allow home directries on any computer so users do not have to have specific computers and they can go in and use any freely avaliable machine. I am open to another suggestions. 
Thanks in advance 
Dean
